75% of the people in Europe live in a city setting. People in cities use three times as much energy as people who live in the country. This has tremendous implications for the environment today and in the future if we do nothing. More and more, developers, consultants, cities, politics will need to imagine intelligent, sustainable cities with smart heating and cooling solutions.

Using renewable energy from both natural and wasted heat sources are great opportunities for more sustainable cooling and heating solutions.

Value natural heat source

Smart cities can value natural heat sources as an advanced and cost effective alternative to fossil fuels. It is available free of charge and offers independence from oil and gas:

Groundwater

Lake water

Sea water

Geothermal Probes

Value wasted heat source

Recent European surveys have demonstrated that there is enough waste heat produced in the European Union to heat the entire building stock. All this waste energy too frequently released into the air or into water bodies. Why not recover it? Smart cities shall value:

Waste heat from data centers

Waste heat from grey waters

Waste heat from industrial process

Waste heat from boilers (wood, gas...)

Waste heat from chillers

Heat recovery potential for smarter cities

Developing smarter cities to anticipate the increase of urbanisation

85°C hot water productionThe combination of Carrier technology and HFO refrigerantenables to offer high temperature PUREtec heat pumps capable of delivering hot water up to 85°C. Selecting the 61XWHZE, you can now supplement traditional boilers in applications such as district heating or industrial processes.The 61XWHZE units can also simultaneously produce chilled and hot water to supplement boilers and replace chillers.

High reliability and certified performancesEvery Carrier 61XWHZE heat pump is factory assembled on a dedicated production line, leak-tested and run-testedin a ISO 140001 and ISO 9001 certified factory. Furthermore Carrier 61XWHZE heat pumps performances have been checked in UTC laboratory during the development phase and are Eurovent certified by an independent laboratory.

Eligible to financial incentivesMany government environmental programs provide financial incentives for heat pumps to support renewable heat production in the industry, the district heating sector and at multi-family buildings: Fonds Chaleur, Certificats d’Economie d’Energie (CEE) in France, Non-Domestic Renewable Heat Incentive (RHI) in the UK.

Low total cost of ownership61XWHZE manufacture is based on large scale component production, standardized production line with leak test and running test of every machine to guarantee an absolute

reliability and peace of mind for our customers. During operation the bearing life time of the compressors is 100 000 hours without expensive mechanical revision and oil renewal. In regards with preventive maintenance, the cost of the replacement of components is limited as well. Only oil filter, motor expansion valves and liquid line core dryer are periodically concerned.

Low environmental footprint61XWHZE heat-pumps are using ultra-low GWP HFO R-1234ze refrigerant in a tight circuit, thus reducing environmental impact of more than 99% compared with previous-generation HFC refrigerants. Furthermore, these units are highly efficient as they reach a COP of 3.0 or more.This results in both direct and indirect CO2 emissions that contribute to global warming.

Carrier 61XWHZE multiple other advantagesCarrier 61XWHZE heat-pumps have many other advantages to meet every single customer needs and project constraints. It includes:

Compact design (from 1000 mm wide) to save space into technical rooms. Multiple water connection arrangements for flexible installation in existing technical rooms. High entering water temperature on condenser side (up to 60°C) to connect multiple units in series counterflow arrangement.

Technical

characteristics

The AquaForce 61XWHZE range covers heating capacities from 200 kW to 2500 kW and up to 12 MW or more in cascade systems when used with Carrier’s plant room management solution.

In a series counterflow arrangement with multiple 61XWHZE heat pumps, heating system efficiency is maximized. The work done (lift) by each compressor is reduced, which significantly improves the efficiency of the heat pumps at full and part load conditions. Such series counterflow arrangement can improve system efficiency by as much as 40% and Carrier’s plant room controls solution ensures efficient and precise control of multiple units to ensure that individual units act as one to meet the applications requirement.

The COP of 61XWHZE heat-pump will vary depending on the temperature difference between the heat source (evaporator side) and the heat sink (condenser side). The work done (lift) by each compressor is reduced when this temperature difference is low thus significantly improving the efficiency of the heat-pump.
